Geranium plant named ‘Fisrocky Orange’

ABSTRACT

A new and distinct cultivar of geranium plant named ‘Fisrocky Orange’, as described and illustrated, and particularly characterized by the combined features of orange, semi-double flowers, rich flowering, dark-green foliage with distinct zonation, medium to strong growth habit forming wide but not very tall plants, and relatively early flowering response.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of geranium plant, botanically known as Pelargonium zonale, and hereinafter referred to by the cultivar name ‘Fisrocky Orange’.

‘Fisrocky Orange’ is a product of a planned breeding program which had the objective of creating new geranium varieties with orange to intense salmon flower color in combination with dark-green foliage.

‘Fisrocky Orange’ originated from a hybridization made by the inventor, Angelika Utecht, in a controlled breeding program in Galdar, Gran Canaria, Spain, in 1992. The female parent was a hybrid seedling, designated no. 1020-6 (unpatented), having salmon-pink, semi-double flowers, dark-green foliage with very weak zonation, and compact plant habit. The male parent was the commercial variety ‘Najda’ (unpatented), which is characterized by orange flower color, early flowering response, medium-green foliage with strong zonation, and relatively compact plant habit.

‘Fisrocky Orange’ was selected as one flowering plant within the progeny of the stated cross by the inventor, Angelika Utecht, in 1993 in a controlled environment in Galdar, Gran Canaria, Spain.

The first act of asexual reproduction of ‘Fisrocky Orange’ was accomplished when vegetative cuttings were taken from the initial selection in the fall of 1993 in a controlled environment in Galdar, Gran Canaria, Spain, by, or under the supervision of, Angelika Utecht. Horticultural examinations of plants grown from cuttings of the plant, initiated in May 1995 in Hillscheid, Germany, and continuing thereafter, has demonstrated that the combination of characteristics as herein disclosed for ‘Fisrocky Orange’ are firmly fixed and are retained through successive generations of asexual reproduction.

BRIEF DESCRIPTION OF THE INVENTION

The following traits have been repeatedly observed and are determined to be basic characteristics of ‘Fisrocky Orange’, which in combination distinguish this geranium as a new and distinct cultivar:

1. semi-double, orange flowers;

2. large inflorescences borne well-above the foliage;

3. dark-green foliage with distinct zonation;

4. medium to strong growth, and a rather wide, but not very tall (high) foliage canopy; and

5. early to medium spring flowering response.

‘Fisrocky Orange’ has not been observed under all possible environmental conditions. The phenotype of the new cultivar may vary significantly with variations in environment such as temperature, light intensity and day length without any change in the genotype. The following observations, measurements, and comparisons describe plants grown in Hillscheid, Germany, and in Langley, British Columbia, Canada, under greenhouse conditions which approximate those generally used in commercial practice.

Of the many commercial cultivars known to the present inventor, the most similar in comparison to ‘Fisrocky Orange’ are the parental variety ‘Nadja’ and the varieties ‘Fischampion’ (U.S. Plant Pat. No. 9,400), ‘Fismega’ (U.S. Plant Pat. No. 9,773), and ‘Fisglori’ (U.S. Plant patent application Ser. No. 09/323,150, abandoned). In comparison to ‘Fischampion’, ‘Fisrocky Orange’ has a lighter-orange tone of flower color and larger inflorescences on stronger, usually green-colored peduncles, while ‘Fischampion’ has thin and partly dark-red peduncles.

In contrast to ‘Fismega’, which has single-type flowers, ‘Fisrocky Orange’ has semi-double flowers of a slightly different color and a somewhat stronger zonation of leaves. Furthermore, the peduncles of ‘Fismega’ have a distinctly stronger, reddish coloration than the peduncles of ‘Fisrocky Orange’.

In comparison to ‘Fisglori’, ‘Fisrocky Orange’ has a lighter-orange, instead of orange-red, flower color and dark-green foliage with stronger zonation, while ‘Fisglori’ has medium-green leaves with weak zonation. Furthermore, the plant habit of ‘Fisrocky Orange’ is normally wider than the more round plants of ‘Fisglori’.

In comparison to ‘Nadja’, which has medium-green foliage, ‘Fisrocky Orange’ has dark-green leaves with narrower and weaker zonation, larger inflorescences, and more vigorous growth.

BRIEF DESCRIPTION OF THE DRAWING

The accompanying photographic illustration shows typical flower and foliage characteristics of ‘Fisrocky Orange’ with colors being as true as possible with an illustration of this type.

DETAILED BOTANICAL DESCRIPTION

The measurements were taken in Langley, British Columbia, Canada, On Jun. 15, 1999, 12 weeks after planting of rooted cuttings into 15-cm pots. The plants had not been pinched. In the following description, color references are made to The Royal Horticultural Society (R.H.S.) Colour Chart. The color values were determined indoors from plants developed in a greenhouse in May 1999 in Hillscheid, Germany.
